EYELETING MACHINE.

Specification of Letters Patent. Patented Oct. 15, 1918.

Application filed July 13, 1914. Serial No. 850,644.

To all whom it may concern:

' ,Be it known that I, SAMUEL I. DERR, a citizen of the United States, and residing at Emaus, in the county of Lehighand State I of Pennsylvania,-have invented certain Improvements in Eyeleting-Machines, of which the following description, in connection with the accompanying'drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. y

This invention relates to improvements in eyeletingmachines and contemplates the provision of a machine whereby blind or invisible eyelets may' be conveniently set in the right and left quarters of a shoe upper after the edges of the latter have been stitched.

Heretofore in this class of work it has been necessary to turn the punched upper nearly inside out in order to locate the setting tools in the desired position. One feature of the invention consists in an upsetting die so mounted that it may be introduced through the lower or unstitched edge of the upper into the required position adjacent to the lacing slit. In the machine herein illustrated the upsetting die is mounted upon the end of a thin bar which is mounted at one side of the setting position and is so arranged that the upsetting die is maintained in alinement with the eyelet carrying set.

Another feature of the invention consists in a movable mounting for the upsetting die so constructed and arranged that it may be moved from one side of the machine to the other, thus facilitating the presentation of a right or left quarter to the machine.

Other features of the invention consist in an adjustable abutment member for supporting the upsetting die during the setting operation and in a stripper for holding the punched part of the upper off the projecting upsetting die and for stripping the clenched eyelet therefrom in order that the feeding of, the work from one position to the next may not be hampered.

These and other features of the invention will be best understood and appreciated from the following description of a pre ferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which,

Figure 1 is a view in perspective of portions of an eyeleting machine embodying the present invention;

Fig. 2 is a fragmentary View on an enlarged scale showing the parts of the machine in the position they occupy at the conclusion of the setting operation, and

Fig. 3 is a fragmentary view of a shoe up per in which invisible eyelets have been set. The invention is herein illustrated as embodied in a foot power eyeleting machine of Well known construction but it should be understood that the invention is in no sense limited to this type of machine but, is of general application.

Referring to the drawings, the machine frame 10 is provided. with a bore in which reciprocates a plunger carrying the lower setting die 12'. A raceway 34 mounted on one side of the frame 10 is arranged to move forwardly into position to deliver an eyelet to the setting die 12 as the latter is lifted and then to move rearwardly to an inoperative position leaving its endmost eyelet upon the spindle of the die.

In the upper portion 14 of the frame, and in alinement with the path of the lower setting die, there is provided a vertical bore for the spindle 16 upon the upper end of which is j ournaled a goose neck bracket 20. The spindle 16 is retained in place by a collar 22 secured to its upper end and a collar 24: secured to its lower end but is free to turn so that the bracket 20 and the parts carried thereby may be swung from one side of the machine to the other. In Fig. 1 one position of the bracket 20 is shown in full lines and another in dotted lines.

Rigidly secured to the lower end of the bracket 20 is a thin die carrying bar 28 which extends at its outer end into alinement with the lower set 12 and carries on its lower face the upsetting die 32. This, it be noted, is provided with a downwardly extending centering projection and is disposed in alinement with the lower setting die 12 and maintains its position throughout the range of movement of the bracket 20., By means of this projection the punched work may be located in alinement with the dies. Secured to the bracket below the bar 28 is a spring stripper 3O perforated at its end to permit the passage of the upsetting die 32'. The stripper normally stands slightly below the end of the die 32 and thus facilitates the re I the lower setting d1e12 is elevated, taking moval of the workfrom the centering projection and its movement from one setting position to the next.

The lower end of the Spindle 16 is threaded for the reception of a cap nut 26 having a rounded end which, pressing upon an acting through the outer part of the upper,

reinforces the upsettin die and its carrier against. the thrust of t e lower setting die 12. The nut 26 thus constitutes an abutment the position of which may be adjusted by rotation upon the spindle. I

In setting invisible eyelets in the left quar ter of an upper the bracket 20 is swung into the. position shown in Fig. 1. The quarter, which has previously been punched, is slipped over the bar 28 and the stripper 30 with itslining side, down until the holes in the two parts arebrought into alinement with the upsetting die 32 with the assistance of the centering projection. In this position the outer or leather portion of the upper, 60 lies above the bar 28- while the lining and facingstrip 70 lie below the end of the stripper 30. With the work thus-positioned an eyelet from t raceway and inserting its barrel throughthe hole in the lining and clenching the eyelet against the upsetting die. When the lower die 12 is depressed the stripper immediately removes the clenched" eyelet from the centering projection on the upsetting die and the work is free to be fed bracket 20 is swung substantially into the into position for the next eyelet. In setting eyelets in the right quarterof an upper the position indicated in dotted lines in Fig. 1 and the operation is carried out as before,

the support for the upsetting die in each case extending outwardly through the unstitched.

lower margin of the quarter being operated upon.

The machine herein described may b einployed with equal facility in the insertion of blind eyelets theonly difference being that the work is presented with the lining side uppermost for this class of work.

Having thus described my invention, I

' claim as new and desire to secure by Letters Patent of the United States:

1. A machine for inserting blind or invisible eyelets having, incombination, a reciproeatory setting die constructed and arranged to'carry an eyelet upwardly and in-' sert it in the work from the lower surface thereof, a bracket mounted to swing about an axis disposed substantially at right.an-

gles to the plane of the workand in alinement with the path of the reciprocatory set- ,tingdie, a thin arm extending inwardly from said bracket, a downwardly facing upsetting die mounted in said arm and provided with axis of said dies.

through the lower of two superposed and punched layers of sheet material, abracket having an inwardly extending arm and mounted to swing about an axis extending in alinement with the path of the movable die, an upsetting die upon said arm,-'

said arm being arranged to be inserted f 1 between saidtwo layers, adjustable means for pressing the material about the hold in the upper layer while the eyelet is being set in the lower layer, and resilient means also supported by said bracket tending to remove the work from the upsetting die,

3. Amachine for setting blind'or invisible eyelets, having, in combination, a forked frame, a reciprocatory setting die mounted in. the lower fork of the frame, a bracket journaledabove the upper fork, and an upsetting die carried by said bracket and disposed below said upper fork and of the reciprocatory die. 7

4.. An eyelet setting-machine having, in

in the path combination, a. frame carrying a reciproca- .tory settingdie and aspindle, a bracket mounted'on' oneend of the spindle and an carried by the bracket.

5. An eyelet setting machine having, in. I combination, a coiiperating pair of eyelet setting-dies, and a stripper pivotally sup abutment on the other, and an upsetting die ported upon'an' axis disposed in alin'ement withsaid dies for movement into difierent positions without disturbing the dies,
